Appnmai mea Apro s, 1899. serian. 711.588. (Inman To t/Z whom it may concern:

Be it known that we, FRANK TALCOT'I, of

and FRED of Farmersburg, in the county of Clayton, State of Iowa, h'ave invent! ed a new and useful Improvement in Milk- Sample'rs, of which the, following is a description, reference beinghad to theaccompanying J. DAUBENBERGER,

drawingawhch are a part of this specification. l

It is frequently desirable lto take a small quantity or sample of nii'lk from a considerable quantity for the purpose -of testing'it to ascertain the amount orproportion of butter fat therein. This testing of milk by using a sample thereof is a common practice at cream-4 eriesin mapvparts of, 1 he country and is conf l monly done by' dippingfa cup or measure into the supply of milk andthereby taking a samzio Vp le therefrom, whichislusuallyfrom, at, or.

" near the. top of the quantity of milk; b ut as 'butter fat is of less specific gravity than the other parts of the milklfit .rises to or toward the surface, so that if a sample is taken from near the top of the milk i t is likely to not bettv fair sample of the quality of the milk throughout the entire quantity.i. It is desirable' that our improved device,

the sample of milk should be taken n otfrom the upper part of the quantity ot" milk alone,

but also 'from the middle or lower portionof thesupply or quantity of milk.

The object of the present inventionis -to v' provide a simple device. convenient to use and adapted to take from 'a quantity of milk a sample thereof also from deeper down-f in the supply,.even near tothe bottom.V al'.

VThe invention consists of thepdevice', its

parts, and combinations ofparts, as hereinlents.

- In the drawings, Figure 1 is a central trans-v verse section of a milk can lor receptacle with also in crosssection', attached thereto. Fig. 2'is a' top plan view of the milkcan and the improved device. Fig. 3 is a crosssection of the device through 1ongitudinal slots therein;

In the drawings, 5 is a 'milkcan or4 recepl tacle, preferably made of sheet'metal and of -wall of the can and turns by- 'into a threaded socket therefor in the bracket .8, the bracket and the faucet being provided not oii'ly near the top', but n the bracket in position,

vertically above the after described audclaimed, or their equiva.

f V"vertically-clongated 'correspondingly weaken the case,

wise. For separating and removingr a sample of the milk in the can 5 we -provideanA lupright tubular case 6, that is mountedl and supported in' the can 5 by means vof brackets 7 and; S.' The bracket 8 'is' preferably constructed with a cup-like socket at its inner end adapted to receivevtherein snugly and liquid-tight the lower'end of the ease 6, advisably turning'into vthe socket in the bracket by means of 'a screw-thread. The bracket is secured tothe wall of the can 5 preferably by means'of a' faucet 9, having a stem that eX- tends'through an aperture therefor in the a screw-thread with `flanges that respectively fit snugly against the inner'and outer surfaces of. the

cam when the stem of the faucet. is turned tov The its seat in the socket in the bracket. bracket and the faucet are a' longitudinal discharge-passage that leads through aregisteringaperture in tlie case G into the chamber of the case. The bracket 7' has a transverse aperture or band-.like construction near its inner end, through which the case 6 passes', and its outer end is placed against and secured to the wall ot'the can conveniently by a screw ,10, turning through the vwall of the can into" the bracket. The bracket? `and the screw Al0 are providedwizth iianges that bear, respectively, against theinner andthe outer surfacesof the can and hold forming a liquid-tight joint.- The bracket 7is bracket S.

The case '6A is provided with a ,plurality of as to provide openings from the-ehambercf the can into the case 6 near its lower extrem# ity andat 'points at various distances above its lower end.- A single elongatedpslot extending from the lower part of the c ase -6 upwardly to or near purpose of these severalapertures, but would and there- -fore a series o'fslots is preferred. Within lprovided with located ata distance slets' l1 1'1, so disposed to its top would serve the IOC g Y v 631,549

, the case G We provide an inner tubular case tion of the tubular valve 12. The valve 12 or tubular valve 12, extending from the botto near its' top,`

tom of the case 6 upwardly which tubular valve is provided with slots 13 13, adapted to register with the slots 11 when in position therefor, but to become non-registering with the slots 11 by a partial rotais also provided with a port 14, so disposed as to register with the passage through the` bracket 8 and the faucet-9 when the tubular valve 12 is turned to the position shown in Fig. 1, in which the Slots 13 are non-registering with the slots 11. A handle 15, attached to thc tubular valvc 12 conveniently by means of a thereto-affixed rigid plug 16, is adapted for rotating the tubular valve to such an eX- tent as is required to make the device operative. Shoulders 17 17 on the top of the valve-case C limit the movement of the tubular valve and serve as a guide by in'eans of which the tubular valve can be readily and accurately moved so as to bring the slots 13 into registration with the slots 11 and rcversely into non-registration therewith, but so that the port 11 will register With the passage through the bracket 18 and faucet 9.

In use when the can has been filled or par- Ytially filled with a supply of milk the tubul lar valve 12 is so rotated as 'to allow milk to enter the case 6 or sample-chamber, and thereupon by partially rotating the tubular valve the sample therein is separated from thc supply of milk in thc can and is discharged from the sample-chamber through the faucet 9. The supply of mik thus obtained'will bc drawn from the quantityoi milk near the bottom of thc can and also atvarious distances upwardly therefrom to, at, or near the l elongated slots and a port near its lower extremity, means 'securing the case. 1n a vertical position in the receptacle,'a tnoular valve fitted yrotatably in the case saidtubular valve being provided with a slot or slots adapted in one position of the valve to register with the slot or slots in the case and with a port adapted in a certain otherV position of ,the tubular valve to register with the port in the Valvecase, and means forrotating the tubular valve limitedly.

2. The combination with a milk-receptacle, of a sampler device comprising a verticallydisposed tubular case in the receptacle said casel being'provided with one or` more elongated slots and a port, a tubular valve having a corresponding, slot or slots and port fitted and rotatable in the case, brackets secured toJthe receptacle supporting thel sampler-case, and a faucet having a passage continuous with a duct from the samplerchamber through the lower bracket.

In testimony whereof we atlx our signatures-in presence of two witnesses.
